' Application filed August 15, 1921. Serial No. 493,016.

To all whom it may concern:

Be it known that I, FRANK E. SMITH, a citizen of the United States, anda resident of Hartford, in the county of Hartford and State ofConnecticut, have invented a new and Improved Marking Stamp, of whichthe following is a specification.

My invention relates to the class of devices employed for printingcharacters of various sorts, as for dating, cancelling, or otherpurposes, and an object of my invention, among others, is to provide adevice of this class that shall be extremely durable and efficient inuse.

One form of device embodying my invention and in the construction anduse of which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in Which-- Figure1 is a view in section through a marking'device embodying my invention.

Figure 2 is a face view of a portion of my improved stamping band.

Figure 3 is a view in section through such portion of my improvedstamping band.

Many of the stamping or marking devices in use prior to my inventionhave embodied endless bands of rubber or similar material having thecharacters integrally formed with said band, such endless bands beinglocated as upon rollers 5-6 supported upon shafts 7-8 mounted in sideparts 9 of a stamping frame comprising, in addition to the side parts, ahousing 10 having a bandle 11 secured thereto in any suitable manner.

In the use of such endless bands of rubber or similar material, when asingle character becomes injured or destroyed it is necessary to renewthe whole band. Moreover, in extended use such band, owing to theinherent qualities of the rubber, becomes stretched to such an extentthat it is useless. By the use of my improved band, when a singlecharacter becomes injured or destroyed for any reason such character maybe readily renewed, and the band as constructed by me will not becomestretched to any appreciable degree.

My improved band as shown in the accompanying drawings comprises a baseconstructed to receive a block composed of rubber or similar materialupon which the characters to be stamped are formed, such base beingcomposed of metal of any suitable character and having a flat restingsurface 12 with knuckles 13 formed on opposite sides of the base and asocket 14: opening outwardly between the knuckles to receive a block 15upon which characters 16 are formed in the ordinary mannen.

Links 17, in the form of oblong loops, are located, as to their sides,in knuckles 13, and these links may be formed of wire, but preferably Istamp them from sheet metal so that they are endless, and a requisitenumber of these bases are secured together by the links to form a bandof the proper length. The blocks 15 hold the links in the sockets in theknuckles 13, and the sockets 14 may be open at either or both ends sothat the blocks may he slid into such sockets by a movement lengthwiseof the base.

While I have illustrated herein and hereinabove described the member onwhich the printing characters are formed as composed of rubber orsimilar material, such member being removably secured to the base, Icontemplate as embodying my invention a structure in which the bases maybe made with the printing characters formed directly thereon, theremovable connections between the bases enabling any base to be removedand replaced by another base whenever the character thereon may becomeinjured. Likewise the material on which the characters are formed may beof any suitable kind.

From the disclosure herein it will be seen that my improved band ispractically indestructible and may be, with ordinary care, usedindefinitely, and that when a character becomes injured or destroyed itis necessary only to renew the member upon which that character isformed.

In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention, together with thedevice which I now consider to represent the best embodiment thereof;but I 100 desire to have it understood that the device shown is onlyillustrative, and that the invention may be carried out by other means.

I claim 1. A stamping band base formed of rigid 105 material withknuckles on opposite sides at the lower part thereof opening from asocket extending into the base to receive a block bearing a stampingcharacter thereon.

2. A stamping band base formed of rigid 110 material formed to provideknuckles on opposite sides at the lower part thereof opening from asocket extending into'the base, and a block located in said socket andcontaining a printing character.

3. An endless band consisting of bases formed'o'f rigid material andshaped toprovide a bottom, side walls and recesses in each of the sidewalls. to enlarge the space between the said side walls, and means forconnecting the said blocks by engagement with the said recesses.

.4..An endless band consisting of bases formed of rigid material andshaped to provide a bottom, side walls and recesses at the edges of thebottom beneath said side walls to enlarge the space between theside-walls near the said bottom, and means for connectingthe said blocksby engagement with the said recesses.

5. base for an endless band; said base being formed of rigid materialand shaped to proxride a bottom and side walls extending at right anglesto said bottom, the said side walls bulging outwardly at their bases toprovide recesses and enlarge the space between the said side walls atthe lower part shaped to provide a channel between side walls thereon,thesaid channel being enlarged at each side to provide space'for thereception of a link thereinJ '7. A base for an endless band shaped toprovidea bottom. sidewalls thereon, a block located between said sidewalls,'and'spaces between said side walls and block to receive alinktherein. r

FRANK E. SMITH.
